Haha, I remember when my math professor called binomial expansions the 'poetry of algebra'. Not sure I agree, but hey, at least it's not calculus. B is the way to go, folks.

Wait, they're asking about the coefficient of x^3? That's easy, it's 40! I can practically see the formula in my head. This exam is a piece of cake!

Binomial expansions, huh? That brings back memories of late nights spent studying for my exams. Alright, let's do this! I'm gonna go with option B, it just feels right.

I remember learning about binomial expansions in my math class. Let's see, the coefficient of x^3 should be the coefficient of the third term in the expansion of (2 + x)^5. Hmm, I think I'll go with option B.
